Which of the following components of xylem is living
(a) Xylem tracheids
(b) Xylem vessels
(c) Parenchyma
(d) None of these

Options

A. Xylem tracheids
B. Xylem vessels
C. Prenchyma
D. None of these

Answer

To determine which component of xylem is living, we need to analyze the options provided:

1. **Understanding Xylem**: Xylem is a type of permanent complex tissue in plants that is responsible for the transport of water and minerals from the roots to the rest of the plant. It consists of different types of cells.

2. **Components of Xylem**:
- **Xylem Tracheids**: These are elongated cells that are dead at maturity and help in the conduction of water.
- **Xylem Vessels**: These are also dead cells that form a continuous tube for water transport.
- **Xylem Parenchyma**: This is the only living component of xylem. It serves various functions including storage and the ability to divide and contribute to healing.
- **None of These**: This option implies that none of the components listed are living.

3. **Analyzing the Options**:
- Option (a) Xylem Tracheids: Not living (dead at maturity).
- Option (b) Xylem Vessels: Not living (dead at maturity).
- Option (c) Parenchyma: Living component of xylem.
- Option (d) None of these: Incorrect since parenchyma is living.

4. **Conclusion**: The only living component of xylem is **Parenchyma**.

**Final Answer**: (c) Parenchyma
